The process of waste paper recycling most often involves mixing used/old paper with water and chemicals to break it down. It is then chopped up and heated, which breaks it down further into strands of cellulose, a type of organic plant material; this resulting mixture is called pulp, or slurry.
Resource recovery can be enabled by changes in government policy and regulation, circular economy infrastructure such as improved 'binfrastructure' to promote source separation and waste collection, reuse and recycling, [5] innovative circular business models, [6] and valuing materials and products in terms of their economic but also their social and environmental costs and benefits.

The de-inking process during paper recycling is also a source of emissions due to chemicals released in the effluent. The European Recovered Paper Council has developed the ‘deinkability scorecard’ so that the printed paper products which have the best recyclability when they are deinked can be identified. [17] [18]

Waste management or waste disposal includes the processes and actions required to manage waste from its inception to its final disposal. [1] This includes the collection, transport, treatment, and disposal of waste, together with monitoring and regulation of the waste management process and waste-related laws, technologies, and economic mechanisms.
Recycling of used paper before the industrialisation of paper production, rag paper was recycled to make low-grade board. A process for removing printing inks from recycled paper was invented by German jurist Justus Claproth in 1774. [2] He practiced together with German paper producer Johann Engelhard Schmid. Today this method is called deinking.
Additionally, the model accounts for the transformation of waste during treatment into secondary waste and residues, as well as recycling and final disposal processes. [2] By including the end-of-life (EoL) stage of products, the WIO model enables a comprehensive consideration of the entire product life cycle, encompassing production, use, and ...
When recycling post-consumer paper, stickies are tacky substances contained in the paper pulp and process water systems of paper machines.Stickies have the potential to contaminate the components either within or around the equipment necessary in the Stages of Manufacturing that a Paper Mill follows in its Developed Process, but would have otherwise excluded it in its routine cleaning and ...
